Detailed Description

A developer would implement this interface to allow immediate mode drawing of primitives, text and markers.

The display system will query for this interface and the Display method will be called.

Remarks: The pointer to the IPrimitiveRenderer should not be stored as its life time is managed by the graphics driver

A callback used to render items using IPrimitiveRenderer.

Member Function Documentation

◆ Display()

GraphicsDriverAPI void Display	(	TimeValue	t,
		IPrimitiveRenderer &	renderer,
		const DisplayCallbackContext &	displayContext
	)

A wrapper of DoDisplay() function.

This function additional checks if current object is disposed.

◆ DoDisplay()

virtual void DoDisplay	(	TimeValue	t,
		IPrimitiveRenderer &	renderer,
		const DisplayCallbackContext &	displayContext
	)

protectedpure virtual

Prototype of user defined render procedure.

User should implement this method, and this method is called when rendering. Note: this interface has reference counter, after creation you need to call AcquireInterface, when you want to release it, call ReleaseInterface.

Parameters

[in]	t	Current time
[in]	renderer	Instance of IPrimitiveRender. User can use this class to draw geometries, markers, and texts.
[in]	displayContext	The display context.
